ADAPTER coaxial, PL to BNC, FxM

Accessory is an adaptor to connect a coaxial cable with a male PL connector to a female BNC connector.

There is a wide variety of connector types for different frequency bands. MSF radio installations use BNC and UHF PL connectors. Satcom installations usually use N and SMB connectors.

Each connector type comes in different models: male, female, for mounting on cables (Aircell 5, Aircell 7, RG58, RG213, RG214 and RG223), or for mounting on a chassis.

Adaptors (combining 2 different connectors) are available in almost all the combinations of male, female, straight or 90º elbow.

PL connectors

• Used by MSF in all HF and some VHF installations (not particularly suitable for UHF)
• Coupling system: plug in and screw
• Impedance: 50 ohms
• Frequency range: HF, VHF, UHF

BNC connectors

• Used by MSF in VHF installations
• Coupling system: bayonet
• Impedance: 50 ohms
• Frequency range: HF, VHF, UHF

N connectors

• Used in UHF installations, and in some satcom installations
• Coupling system: plug in and screw
• Impedance 50 ohms

When ordering cables, it is important to specify the connectors you need:

• VHF installations: BNC and UHF PL connectors
• HF installations: UHF PL connectors only
• satcom installations: N and SMB connectors

A connector should never carry the weight of a cable. A cable must be connected and fastened as indicated in the diagram.

Never use tools to tighten a connector.

To unplug a cable, pull on the connector, never on the cable.

Unplug the connector during a thunderstorm and place the coaxial cable outside the building.

Use vulcanizing tape to protect connectors located outside against humidity.

Soldered connectors are preferable to crimped connectors, as the latter give poor signal quality after prolonged use.
